Abstract
Abstract Spray mixing nozzle for reacting acid and base having a central pressurized gas channel, at least two surrounding annular channels for acid and base and an outer annular channel for pressurized gas. The pressurized gas forcefully unites the acid and base into a spray at the nozzle outlet. The spray mixing nozzle is provided with a water spray, directed toward the spray mixing nozzle orifice, to prevent crust formation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A spray mixing nozzle comprising: a nozzle body having a nozzle outlet, said nozzle body including a central channel for directing pressurized gas to the nozzle outlet, at least two annular channels surrounding the central channel for separately directing liquid to the nozzle outlet, an outer channel surrounding the at least two annular channels for directing pressurized gas to the nozzle outlet, said pressurized gas from the central channel and the outer annular channel forcefully mixing liquids flowing through the at least two annular channels into a fine spray; and a water spray nozzle mounted to the body of the spray mixing nozzle, said water spray nozzle being mounted to direct a stream of water against the nozzle body in the area of the nozzle outlet.
Claim 2
Dependent Claim
126 words
A spray mixing nozzle comprising: a nozzle body having a nozzle outlet, said nozzle body including a central channel for directing pressurized gas to the nozzle outlet, at least two annular channels surrounding the central channel for separately directing liquid to the nozzle outlet, an outer channel surrounding the at least two annular channels for directing pressurized gas to the nozzle outlet, said pressurized gas from the central channel and the outer annular channel forcefully mixing liquids flowing through the at least two annular channels into a fine spray; and a water spray nozzle mounted to the body of the spray mixing nozzle, said water spray nozzle being mounted to direct a stream of water against the nozzle body in the area of the nozzle outlet.
Claim 3
Dependent Claim
32 words
The spray mixing nozzle of claim 1 wherein the water spray nozzle is mounted to direct the water spray obliquely inwardly against the front of the nozzle body at the nozzle outlet.
Claim 4
Dependent Claim
34 words
The spray mixing nozzle of claim 2 wherein the water spray nozzle is mounted to direct the water spray against the front of the nozzle body at the outlet of the outer annular channel.
Claim 5
Dependent Claim
31 words
The spray mixing nozzle of claim 3 wherein the nozzle body includes a cylinder which surrounds and extends beyond the nozzle outlet, said water mixing nozzle being mounted within said cylinder.
Claim 6
Dependent Claim
32 words
The spray mixing nozzle of claim 3 wherein the outlet of the water nozzle is mounted at a distance of from 5 to 50 cm. away from the spray mixing nozzle outlet.
Claim 7
Dependent Claim
31 words
The spray mixing nozzle of claim 1 wherein the water spray nozzle is mounted to direct a stream of water at the edge of the nozzle body at the nozzle outlet.
Claim 8
Dependent Claim
179 words
A spray mixing nozzle comprising: a nozzle body having a nozzle outlet and a conically shaped central portion which extends beyond the nozzle outlet, said nozzle body including a narrow central channel for directing pressurized gas to the nozzle outlet, at least two annular narrow channels surrounding the central channel for separately directing liquid to the nozzle outlet, and an outer inwardly tapered annular channel surrounding the at least two annular channels for directing gas to the nozzle outlet, said outer channel and said at least two annular channels terminating at the nozzle outlet, the ratio of the throughput cross section of the central channel to the throughput cross section of the outer annular channel being from 1:3 to 1:10, said central channel terminating in said conically shaped central portion and said outer channel being inwardly directed toward the outlets of the at least two annular channels to provide a stream of pressurized gas from the central channel and the outer annular channel to forcefully mix liquids flowing through the at least two annular channels into a fine spray.
Claim 9
Dependent Claim
179 words
